but almost all (if not all) of these guns are made in the United States.
the US has something like half of all the world's guns.

But the guns that do the most damage among the cartels are not manufactured in either Canada or Mexico
Usually China, Bulgaria, or some other AK 47 hotspot.

I'm trying to find out. I got this so far:
Is gun theft a part of the illegal gun problem? Yes, gun theft is one of the ways guns are diverted to the illegal market. The ATF reports that over 13,000 guns are lost or stolen from dealers nationwide each year. Estimates show that as many as 32% of crime guns are acquired through theft.5 6www.mayorsagainstillegalguns.org/html/about/faq.shtml
